    AbstractCardiovascular system changes with aging, and these changes are modified by arteriosclerosis-risk factors, i.e., hypertension and diabetes, as well as arterial-cardiac interactions. Regarding age-related changes in the cardiovascular system, Lakatta et al. reported morphological and functional changes that are specific to the cardiovascular aging and are distinct from arteriosclerotic changes. After then, various studies on the mechanism of aging of the cardiovascular system have been performed from the viewpoint of cellular aging, endothelial or endocardial function, and fibroblast. Aging-related changes in the cardiovascular system include death and dysfunction of cell, and matrix fibrosis, but these can also be induced by various causes other than aging. To elucidate the relationship between aging and remodeling of the cardiovascular system, firstly, it is necessary to clarify the phenomena of cellular aging. Changes also differ between the heart and arteries, and there are time lags between aging and aging-associated morphological and functional changes in the cardiovascular system: some changes appear early (early type) or later (delayed type) and some changes occur at the same speed with aging (linear type). In this report, the latest findings concerning aging-associated functional and morphological changes in the arteries and the heart are reviewed and the studies are summarized. Arteries and the heart change with aging while interacting with each other. These arterial-cardiac interactions are also described.Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.
